chine commonly known as the Remington,

as will be hereinafter more particularly described.

Referring to the accompanying drawings, which are made a part hereof,and on which similar letters of reference indicate similar parts, Figurel is a top or plan view of a carriage embodying my said invention,certain portions being broken away to show the operating parts moreclearly; Fig 2, an under side plan of the same; Fig. 3, a longitudinalvertical section through said carriage and the frame of the machine onthe dotted line 3 3 in Figs. 1 and 2, a portion of the platen-head beingbroken away to show the ratchet; Fig. 4, a detail perspective view ofthat portion of the carriage-frame containing the joints; Fig. 5,adetail view showing the spacing-levers in section on the dotted line 5 5in Fig. 1; Fig. 6, a detail view looking toward the left from the dottedline 6 6 in Fig. 1; Fig. 7, a detail section looking up from the dottedline '7 7 in Fig. 8; Fig. 8, a detail vertical section on the dottedline 8 8 in Fig. 2; Fig. 9, a similar section on the dotted line 9 9 inFig. 2, and Fig. 10 a detail section looking downwardly from the dottedline 10 10 in Fig. 8.

In said drawings, the portions marked A represent the frame of themachine; B, the frame of the carriage; C, the platen; D, a rock-shaftcarrying the spacingdevers and connected with the spacing mechanism; 1,the feed-roller; F, the scale, and G the papertable.

The machine-frame A is of the Remington construction, and is shown onlyto illustrate the position and manner of operating my improved carriage.Portions are broken out for the purpose of allowing the invention to beshown on a large scale, the principal views being nearlyfull size.

The carriage-frame B is the usual rectangular frame of a suitable sizeand proportion, and is provided with the hearings in which the shaftsand rods carrying the mechanism are journaled. On its front is mountedthe mechanism by which it is connected to the shiftingrod A, whichmechanism consists of a concave-faced vertical roller Z2 and ahorizontal roller b, arranged to bear on the top and side of said rod A,on which the front of the carriage rests and travels, these rollersobviating all friction between the parts. It also has the indicator B,secured to its front side at this point, which consists principally of adouble piece of metal, the rear portion b of which extends down to aposition that brings its point below the rod A, and is formed with aforwardly-inclined face, which when the carriage is dropped down strikesthe rod A and serves to direct it into position on said rod.

The shifting mechanism by which the carriage is operated back and forthconsists of the rod A, connected to the rock-shaft A by means of thearms a, said rock-shaft being operated by means of the lever A connectedto one end of a double-ended laterally-projecting arm a, which isrigidly secured to said rock-shaft and projects out from each sidethereof by means of a connecting-rod a a spring A being connected to theopposite end of said arm Ct at one end, and to the frame at the other,for the purpose of returning said rock-shaft and through the connectingparts the carriage, as in the Remington machine.

On the rear side of the main portion of the frame B are formed twoupwardly and rearwardly projecting arms 13 to the outer ends of whichare pivoted short downwardly-proj ecting arms in the lower ends of whichare formed 'journal-bearings, preferably being provided withjournal-boxes Z), in which the carriagerod A" is mounted, saidcarriagerod being pivoted in the usual manner to the frame of themachine. The journal-boxes Z1 stop to limit their motion, which consistsin forming a notch 17 in the top of one part and mounting a pin barranged to rest in said notch, in the other part. (See especially Figs.3 and 4..) The two short arms B are connected byabar B preferably castin one piece therewith, in which is formed suitable bearings for thetrucks 1)", arranged to run on the top of the rod A and support thecarriage. (See Figs. 1 and 4.) The rack B is in main of the usualconstruction, but has a rearwardly-projecting flange W, a portion of theunder face of which is formed smooth and a portion notched. Secured tothe frame of the machine and extending up at the rear of this flange isa standard A, at the top of which is mounted a pivot-bolt (1?, on whichis mounted a roller a and a cam 61, said roller being arranged to bearon the smooth portion of said flange and the said cam being arrangedbeneath the notched portion. Said cam is formed with a heavy portionbehind the pivot, which operates to hold its point against the notchedportion of said flange. Thus as the rack travels forward its rearportion rests upon the roller a but when it is started back the point ofthe cam engages with the notched portion of the flange which operates toturn said cam up and lift said rack free from engagement with the dogand support it in this position during its travel backward, a stop-pin abeing inserted in the standard A in position to stop said cam in therequired position. When the carriage starts forward again,the cam dropsback and permits said rack to fall upon the roller a and again intoengagement with the dog, as will be readily understood. On the top ofthe rack 13 is formed a handle 5 by which said rack may be lifted out ofengagement with the dog when it is desired to slide it forward anyconsiderable distance without taking the time to do ,it one space at atime. That portion of the ends of the frame 13 in which are formed thejournals and where the spacing mechanism is connected to theplaten-shaft is preferably formed hollow, or consisting of adoubleflanged bar, the flanges extending down on the inside a=sufficientdistance to cover all this mechanism. (See Figs. 2 and 3.) A trip I),for operating the alarm-bell, is adj ustably secured to the front sideof the rack B by means of a screw inserted therein through an elongatedslot 12 extending through said rack horizontally. (See Fig. 6.) Byloosening the screw said trip can be adjusted to the desired positionand there secured by tightening said screw, as will be readilyunderstood.

The platen C is in itself of the usual construction, my improvementsrelating particularly to the mechanism by which it is revolved to makethe spaces. It is journaled in the usual position on the shaft 0 andprovided with the right platen-head C and a left platen-head C The hubon the left platen-head C is notched around the edge is preferably thepush-button 0 of its face, and a correspondingly-notched collar (1' ismounted around the shaft and arranged to engage with said hub, it beingprovided with perforated ears on its sides and mounted to slide on pins0, projecting out from the frame, a coiled spring 0 being interposedbetween the collar and the frame, by which said collar is at-all timesheld against the hub, and the platen thus secured from rotating, exceptwhen force is applied. As will be understood, the notches in this huband collar are formed to correspond with the number of notches in theratchet-wheel by which the platen is rotated. This mechanism at the leftend of the platen is preferably inclosed in a cylindrical shell B formedon this end of the frame, whereby it is not only kept out of sight, butout of the Way of dust and dirt. The right platen-head C is secured tothe platen in the usual way. The ratchet-wheel O is mounted on the shaft0' on the inside of said head 0 to which it is secured when rotating inone direction by means of a springpawl 0 and is held in position againstsaid head by means of brackets 0 secured to said head and extending downover the edge of.

said ratchet-wheel. Around the perforation in the center of saidratchet-wheel is found a series of notches 0 with which pins or lugs con theshaft engage and secure said ratchetwheel thereto. The shaft 0 ismounted to slide in its bearings, being held toward the right, so thatthe pins are in engagement with the notches in said ratchet-wheel at alltimes by means of the spring (3, mounted between the inner flange of theframe B, through which it passes, and an arm secured rigidly to saidshaft toward its outer end. Thus when it is desired to disengage theplaten from the shaft for the purpose of turning it back, said shaft canbe pushed in by means of a push-button c on its outer end until the pinsare disengaged from the ratchet-wheel, which permits said platen to berevolved freely. A short arm 0 is rigidly secured to the outer end ofsaid shaft in a position between the two flanges of the frame, it beingpreferably secured in position by flattening a portion of the shaft atthis position for a sufficient distance to receive said arm, which isformed with the corresponding hole, and secured thereon by means of anut screwed against it, which nut (See especially Figs. 8 and 10.)

The rock-shaft D is journaled in suitable bearings at each end of theframe, just in front of the platen, and in addition to the spacingmechanism carries idler-pulleys d for the feed-roller bands, as will bepresently described. At the right-hand end of this shaft it is providedwith a rearwardly-projecting arm D formed with a bifurcated end, betweenthe forks of which is mounted a bearing-pin cl which is arranged inaslot formed in the end of the arm 0 mounted on the shaft 0 of theplaten. '(See Fig. 3.) At its center it is provided with a series oflevers D, D

ICC

and D arranged to rest against the flat spring B which projectsrearwardly from the front bar of the frame B, to which it issecured. Thelevers are so adjusted upon the rod that when forced down against thetop of the frame, (a rubber cushion 17 being preferably arranged inposition beneath said levers, so that they will strike it when forceddown, thus deadening the sound and relieving the frame from the force ofthe stroke,) they will travel a distance necessary to re volve theplaten three spaces. They are secured to the rock shaft by means of aspline or pins (P, the lever D being formed with a notch in its bearingof a length equal to twothirds of its full motion, and thus when it isforced down it does not commence to rotate the rock-shaft until it hastraveled two-thirds of the stroke, thus rotating the platen only onespace. The lever D is mounted in a similar manner, except that the notchis equal to one-third of the motion instead of twothirds, and-thusoperates to rotate the platen two spaces. The lever D is rigidly securedto said rock-shaft, and thus rotates it the entire distance and operatesto rotate the platen three spaces. By this arrangement I provide a veryconvenient means, by which I am able to space either one, two, or threespaces, as may be desired, without shifting or changing any mechanism. Astop-pin b is provided in the frame to extend out under the arm D inposition to limit its downward motion and stop it in exactly theposition desired.

The feed-roller E is journaled in swinging bearings e, pivoted to theframe, as is usual on the Ren'lington machine. It is connected at eachend to the idler-pulleys d on the shaft D by means of the rubber bandsE, which pass under and bear against the under side of. the platen andhold the feed-roller in contact with said platen in the usual manner.

The scale-bar F extends from one end of the frame to the other, to whichit is rigidly secured in the usual position. The guards F are securedthereto and extend forward over the bands E, which they protect fromcontact with the ribbon, as usual. They are also formed with flanges ontheir forward ends which project up each side of the idlerpulleys (l,and thus steady said pulleys and the bands in position.

The paper-table Gis mounted 011 the frame B in the usual position andwell-known manner. A paper-guide G is supported from the front bar ofthe frame, extending rearward to the desired position beneath theplaten, where it is provided with. a roller g, and then extended up infront of the platen.

The operation of my said invention, is as follows: \Vhen it is desiredto shift the carri age from the position it occupies when using thelower-case to that which it occupies when using theupper-case,letters,the shifting-lever A is forced down, which operatesthrough the connecting-rod. a arm a, rock-shaft A and arms a to throwback the rod A, on which the front of the carriage rests, whichoperation throws back the entire carriage on the carriage-rod A from theposition shown in the whole lines in Fig. 3 to that shown in dottedlines, the backward motion being continued until the arms a strike therear side of the notch a in the frame A, through which they extend. Thecarriage is held in this position in the same manner that the slidingframe in the old construction of the machine is held until it is desiredto bring it forward, when the lever is released and the carriagereturned by the spring A until the arms a strike against the front ofthe notch a", which notch is formed to thus properly limit the motion ofthe carriage. By this arrangement the entire carriage is operated backand forth instead of a separate sliding frame, and many of the parts ofthe old machine are thus done away with. \Vhen the carriage is liftedup, it tilts back on the rod A the arm B being prevented from fallinginto a horizontal. position in relation to the arm 1-3 by means of thenotch b and pin b which'serve to limit the motion of the joint betweenthe parts B and B as before described, said notch being of a length onlysufficient to permit the carriage to be shifted freely. \Vhen it isdesired to rotate the roller for the purpose of spacing between thelines, one of the levers D, D or D according to whether one, two, orthree spaces is desired, is forced down. In practical use the lever Dwhich operates to rotate the platen two spaces, will be most used, andby giving a detailed description of its operation the operation of theothers will be readily understood. In forcing it down, as before stated,the first one-third of the movement does not move the rock-shaft, but atthis point the shoulder of the notch in the bearing comes in contactwith the spline or pin on the shaft, which operates to rotate saidshaft, which throws the arm D on its end upward, carrying with it thearm 0 secured on the end of the shaft 0, which operates to rotate saidshaft, and through said shaft the ratchetwheel 0 mounted thereon, whichratchetwheel, being secured to the platen-head C operates to rotate saidplaten the desired distance. The lever being released, the spring Boperates to throw it back until the arm I) strikes the stop-pin b whichis mounted in the frame under its outer end, which opera tion returnsthe shaft 0 to its former position, carrying with it the ratchet-wheel Gwhich is allowed to slip under the springpawl 0 when turning in thisdirection, the platen being held .in position by means of the notchedhub on its opposite end and the notched collar 0, which is arranged toengage therewith, as before described. Then it is desired to turn theplatenin the opposite direction, the shaft on which it is mounted ispushed in until the pins 0 are disengaged from the ratchet-wheel 0 asbefore described, when said platen can be freely revolved the desireddistance, and the shaft, being then IIO released, is returned by meansof the spring move endwise, and feeding mechanism en-.

gaged with and disengaged from said shaft by the endwise movement of thelatter.
